LOGKU Application filed June 16, 1922. Serial No. 568,832..

To all wiwm it may concern:

Be it known that l, EUGENE R. WEBER, citizen of the United States.residing at Rochester. in the county of Monroe and State of New York,have invented certain new and useful Improvements in Locks; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, forming apart of this specification, and to the reference numerals markedthereon.

This invention relates to locks and more particularly to the varietyhaving a rotary cylinder or plug extended through the wall portion orother supporting means to which a lock is attached to receive a key orother operating device, the chief object of the invention being theprovision of simple and eflicient means for effectively preventing thecylinder or plug from being forcibly displaced for obtaining access toor disabling the lock. To these and other ends the invention resides incertain improvements and combinations of parts all as will hereinafterbe more fully described, the novel features being pointed out in theclaims at the end of the specification.

In the drawings:

Figure 1 is an exterior view of a door having a lock embodying thepresent invention supported on the interior side thereof;

Figure 2 is a sectional view on the line of Figure 3, showing theconstruction for securing the cylinder or plug against displacement fromthe door;

Figure 3 is an elevation of the parts shown in Figure 2 as appearing atthe interior side of the door;

Figure 4 is a section on the line i a of Figure 2;

Figure 5 is a view of a door having a lock applied thereto embodying amodified form of the invention;

Figure 6 is a sectional View on the line 6 --6 of Figure 7;

Figure 7 is a sectional view on the line 7 of Figure 6 illustrating theconstruction shown in Figure 5 for securing the cylinder or plug againstdisplacement.

Similar reference numerals throughout the several views indicate thesame parts.

The invention is disclosed in the present instance, by way ofillustration, as embodied in a lock of a variety particularly adaptedfor use on the closure or door of a safe deposit box, the door beingrepresented in the drawings at 10, having the lock 11 secured to theinterior side thereof in any suitable manner, for example, by screws 12.it has been found desirable to construct locks of this character with acylinder or plug extending through an open.- ing 13 in the door to theeuterior side of the latter for rotation by a key or other operatingmeans. Ei'ecurity b0 doors of this type are commonly constructed ofsteel and. those desiring to forcibly open. the door for unauthorizedpurposes have heretofore found it possible in most instances to forciblydisplace the lock plug, either by extracting the same at the exteriorside of the door or by driving the plug inwardly through the lock,thereby securing access to the lock or disabling the same and thusunlocking the door.

The present invention provides an improved construction for effectivelypreventing the forcible displacement of the lock plug in this manner,while at the same time interposing no interference with the normaloperation of the plug, or the authorized removal of the look from theinside of the door for repair or replacement. To this end either thewall of the opening 13 in the door which receives the lock plug,indicated at 14, or else the circumferential surface of the latter, orboth, have formed therein an arcuate channel or groove 15 cooperatingwith means engaging the adjacent surface of the other member to securethe plug means against displacement while leaving it free to rotate inthe opening 13. In the present instance this construction is given theform of a channel or groove 15 in the circumferential surface of theplug means for cooperating with ball means or members l6 engaging in acorresponding groove 17 in the wall of the opening 13 of the sup portingmeans. These opposing grooves thus form in effect a ball race which issubstantially filled with the ball members 16, as shown in Figure 4:,effectively locking the plug means against displocement in eitherdirection from the opening in the door. The balls 16 may be inserted, orremoved, if necessary, after the plug means has been located in itsopening in the door,

through a passage communicating with the hall race and openingexteriorly through a surface of the plug means or of the sup portingmeans or door inaccessible from the outside of the latter. Tn thepreferred form this passage is shown at 18 formed in the plug meansitself, having one end turned angularly into comn'iunication with theball race. and the other opening at the inside of the plug and closed byany suitable means, such, for example, as the threadee stopper 19. Inthis case an additional ball 20 placed in the passage to prevent theballs in the race-way from entering the lat ter, except when the stopper19 is removed.

To increase the difficulty of driving the plug inwardly of the door, theplug is preferably provided with an annular shoulder 21 cooperating witha similar shoulder in the sides of the opening 13. This increases theresistance of the plug to force applied to displace the same inwardly,it being more difficult to pull the plug outwardly of the door becauseof the difhcnlty of applying the necessary force thereto.

lVhile the plug means 1% described above may be constructed integrallywith the cylinder or plug which extends through and operates the lock,it is preferred to form the plug in sections. That is to say the plugmeans 14- is preferably extended to a plane 21 spaced somewhat from theinner surface of the door, in abutting relation with the outer end ofthe plug 22 extending through the lock, these plug sections beingseparably connected for conjoint rotation by any suitable device, such,for example, as the dowel pins 23 in the plug means 1 engaging incorresponding openings 24 in the lock plug 22. By this arrangement theplug means 14 and the plug 22 rotate as one while the lock is in placeon the door, and the lock may be readily detached if found necessarywithout removal of the plug means or section 14.. In the modificationdescribed above the parts are assembled by first placing the plug means14% in position in opening 18 of the door and then inserting the ballmembers into position through the passage 18, which is then closed bymeans of the stopper 19. When the plug means has thus been secured inposition, the lock proper may be attached to the door, the plug means14: being rotated to bring its dowel pins 23 into registry andengagement with the openings 24 of the lock plug 22.

Various modifications in the specific embodiment of the invention havebeen contemplated; Thus in Figures 5 to 7 the walls of the opening 25receiving the plug means. 26 and the circumference of the latter areprovided the one with a circumferential groove 27 and the other withsockets 28 for the-ball members 29, the sockets in the present instancebeing formed in the plug stopper 31.

means, although, of course, this arrange ment might be reversed tolocate such sockets in the supporting means or door 10. The passage 3for inserting the balls 29 in this modification is arranged to openexteriorly through the end of the door, being closed by The plug means,as before, connected by dowel pins 32 with the plug of the lock, theparts being so disposed and arranged that when the lock is in place, thelimited movement of its plug 22correspondingly limits the rotation ofthe plug means 26 so that the key opening 33 moves throughthe smallangle included by the angular line c to prevent the ball members frombecoming displaced from their sockets and entering the passage 30.

In the assembly of this modified construction the plug means 26 islocated in its opening 25 in the door and the ball members inserted intheir sockets through passage 30, the plug means being rotated to theproper position to receive the ball and the door'being tilted so thatthe balls drop through the passage by gravity. When the lockis thenattached to the door with its plug 22 in engagement with plug means 26the move ment of the latter-is limitedin the manner described, so thatnone of the ball members are brought during the operation of the locksuiiiciently into registry of the opening to permit the displacement ofthe balls, Figure 7 showing one of the limiting positions of movement.shown in the present instance in engagement with one of the movableparts for cooperation with a groove of the other it is obvious thatelements other than ball members might be employed for this purpose. andplug means may of course be supported on the door frame or otherstationary part instead of on the door.

The invention thus provides a. simple and practical construction for thelock plug -or cylinder, and door or other supporting \Vhile ball membershave been loo The lock means for the lock, which effectively preventsaccess to or injury of the lock bythe unauthorized forclble displacementof the plug either outwardly or inwardly of the door. while the lock'proper may be as readily assembled or detachedas' before.
